Abstract
Abstract A splicer bar is provided for fastening together two inverted T-shaped runners. The splicer bar spans the junction between two runners and the splicer bar is fastened to the vertical web of both runners. Each runner has spaced apertures in its vertical web and the splicer bar has snap fasteners that will fit into these apertures to hold the two runners in parallel alignment and fixedly fastened together.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
154 words
A joint structure between two runner members wherein the two runner members are inverted T-shaped runner members with a vertical web, each runner member having identical ends wherein two apertures are positioned in each vertical web at the ends of each runner with the apertures spaced a slight distance apart and positioned in alignment along the vertical web, a splicer bar for fastening together the ends of two adjacent runners, said splicer bar having a pair of lugs means on each end of the splicer bar, said pair of lugs means being such that one pair of lugs means engages the two apertures on one end of one runner and the pair of lugs means on the other end of the splicer bar engages the two apertures on the adjacent abutting runner member to fasten together said runner members said lugs being resiliently mounted to snap into and out of engagement with said apertures.
Claim 2
Dependent Claim
154 words
A joint structure between two runner members wherein the two runner members are inverted T-shaped runner members with a vertical web, each runner member having identical ends wherein two apertures are positioned in each vertical web at the ends of each runner with the apertures spaced a slight distance apart and positioned in alignment along the vertical web, a splicer bar for fastening together the ends of two adjacent runners, said splicer bar having a pair of lugs means on each end of the splicer bar, said pair of lugs means being such that one pair of lugs means engages the two apertures on one end of one runner and the pair of lugs means on the other end of the splicer bar engages the two apertures on the adjacent abutting runner member to fasten together said runner members said lugs being resiliently mounted to snap into and out of engagement with said apertures.
Claim 3
Dependent Claim
85 words
The structure of claim 1 wherein the lugs are composed of two oppositely disposed projections, one positioned above the other, said projections being provided with enlarged ends and a resilient mounting means which permits the enlarged ends to be forced into a contracted state and then subsequently an expanded state to retain the spacer bar in position with the two oppositely disposed projections engaging opposite sides of an aperture to fix and retain the spacer bar in engagement with the vertical web of the runner.
Claim 4
Dependent Claim
102 words
A splicer bar for use as an engaging means for ceiling runners, said splicer bar being an elongated flat bar structure having two sets of lugs thereon, the lugs being in pairs in each set and being at each end of the splicer bar and projecting from one planar surface thereof, each of said lugs being composed of two projections, one positioned above the other, said projections being provided with enlarged ends and a resilient mounting means which permits the enlarged ends to be forced into a contracted state and then subsequently, an expanded state to retain the splicer bar in position.
Claim 5
Dependent Claim
102 words
